Here the continuation.
2 The influence of the zero.
The zero is nor red or black. The zero is the contrary EC of the bet. Bet black the zero is red. The France roulette has a particular rule for the zero, the so-called single or double En Prison rule. After a zero the bet is divided by two. This feature is a very important advance for the France roulette. If you have the choice, never play the double zero roulette
In the Martingale system, the zero gives an extra profit. The maximum extra profit is, when the zero falls in the ninth step.
3 The Martingale system.
In the casino, you see very often, the player starts a Martingale session after 6 consecutive colours. The expectation is, in the next 6 spins the colour is changed.
A 12 spins sequence has a probability of once on 4096 spins. The risk is very low. The disadvantage is the possibilities are very rare.
A second Martingale system is to wager on one colour.
The expectation of a 10 steps Martingale wager is that in the next ten spins the colour changes. The risk of a loss is only 0,195%.
The third Martingale system is my
S (hoe) S (hine) B (oy) system.
A 10 red sequence has the same probability as a random sequence. I wager a 10 random sequence shall not repeat. The risk is the same as the one colour system. The advantage is that after every hit you start with a new random sequence. You never have to wait for a new opportunity.
You have stroked against a 20-spin sequence like 20 consecutive red after a loss session.
I have programmed the SSB system in Excel. The program is also suitable for other experiments.
The graph shows the results of a 250-spin sample with 10-step progression. The average profit is 140 units.
The program shows the graphs of the bets and the profit per spin. It is very easy to various the numbers of steps. I use in my program 10 steps in connection with the table limit.
